All versions

Specification

With reduced outer diameter for improved installation. For producing a lasting, heavy-duty female thread. With an additional screw grip (SG) area. Made of stainless steel.

Perfect combination of space-spacing and wear-resistant thread strength

In low-strength metal materials

In plastics

Optimal force distribution

Flexibility of the thread inserts compensates for pitch and angle errors

Thread insert sits securely

Minimised thread friction torque and minimised torsional stress

Increased corrosion resistance

Space and weight minimisation

Smaller number of required connection points and/or reduced screwing dimensions

Costs minimised

By reinforcing the thread, which effectively minimises the repair costs

Integrated loss protection

Proof of Performance

The clamping torques are comparable with the values of DIN 267 Part 15 or DIN EN ISO 2320.

Application

Instructions

A resistant thread in 4 steps:

Step 1:

Drill a core hole or drill out the damaged thread

Step 2:

Create a receiving thread

By cutting using screw tap

Without cutting using thread moulding for an even more resilient receiving thread

Step 3:

Set the thread insert

The helical insert can be mounted both mechanically and also by hand using the corresponding screw-in tool.

Step 4:

Break the pin

Separate the follower pin by tapping gently on the predetermined break point with a pin breaker, and then remove. Automatic pin breakers are also available for series production.
